After tooth extraction, because the anesthesia effect has not yet disappeared, there may be slight discomfort in the face, which does not need to be treated, and can be treated when the anesthesia effect disappears. At the same time, attention should be paid to the amount of bleeding from the tooth socket, and a large amount of bleeding needs to be treated by a doctor. After the anesthetic effect wears off, there may be slight pain in the periodontium, and an ice pack can be used to apply a cold compress to the affected cheek, which can relieve the pain. Common clinical precautions include: 1. After tooth extraction, the doctor will place sterilized gauze rolls or sterilized cotton balls on the trauma surface and make the patient bite down slightly to compress the bleeding, which can be taken out by himself after 30 minutes. 3. Do not lick or suck the wound with the tip of your tongue to prevent the blood clot in the wound from falling off and causing bleeding or even dry socket; 4. It is normal for a small amount of blood to ooze out of the wound on the day of extraction, and there will be blood in the saliva. Patients should be careful not to touch the incision with their hands, and if a lot of bleeding occurs, they should seek medical attention promptly; 5. If the incision is too painful after the anesthesia wears off, pain medications such as ibuprofen and acetaminophen can be taken as prescribed by the doctor; 6. If the tooth is extracted during the acute inflammation period or the extraction of complex teeth or obstructed teeth, antibiotics can be given before and after the extraction to control the infection, and patients need to follow the doctor’s prescription for medication; 7. If pain occurs again 2-3 days after the operation, or if the pain increases, infection of the wound may occur, and the patient should seek medical examination and symptomatic treatment; 9. At the same time, foods such as seafood, beef and mutton should be avoided in the near future, and smoking and alcohol consumption should be avoided.
